Description

The USA Standard Gear ZA K630818 is a robust replacement axle shaft kit specifically designed for the Dana 44 differential. With a precise length of 29-1/4 inches and a 30-spline count, this component is engineered to meet or exceed original equipment specifications, ensuring a reliable fit and dependable performance for your Jeep. Constructed from advanced alloys and subjected to state-of-the-art heat-treating processes, the ZA K630818 axle offers enhanced strength and durability for demanding off-road conditions. This comprehensive kit includes the axle shaft, wheel bearing, wheel seal, studs, and lug nuts, providing everything needed for a complete axle replacement or upgrade. This axle shaft kit is compatible with Jeep TJ and Jeep Wrangler models from 1997 to 2006. The shaft is for the rear left position and features double-drilled bolt patterns for both 5x4.5 in. and 5x5.5 in. applications. The manufacturer emphasizes that fitment should be confirmed to reduce the risk of ordering the wrong product, and if fitment is confirmed by their team and the product does not fit, they will arrange a return with no restocking fees provided the item is in like-new condition.
